OK, serious attempt:
It isn't that much crazier than a lot of other "serious" religions.
See magic underwear, pillars of salt and racist people who didn't understand what Christ was actually saying. In plain Aramaic.
Well, there's also religions based on movies. "Dudeism," anyone? "Matrixism," anyone?
There's even a collective (underground but) of "Jedi's" that believe that stuff. While Scientology is crazy, people will believe whatever they want (or don't want) to believe.
